W'EFT-REPLENISI-IING LOOM.

Specification of Letters Patent.

Application filed December 20. 1909.

Patented 'Uct. ill, will.

Serial No. 534.049.

To all whom 'it'mai concern:

lie it known that I, EPPA H. RYON, a citizen of the l mited States, residing at oreester, in the county of lVorcester and State of Massachusetts, have invented eertain new and useful Improvements in \Veit Replenishiug Looms, of which the following is a specifieatimi.

lily invention relates to weft replenishing looms, and more particularly to a filling detector or feeler mechanism for weft replenishintlooms. which is preferi'dily located at the magazine end of the loom,on the loom side or end frame. ho filling detector or lieeler is adapted to feel through an opening in the front wall of the shuttle and engage with the lilling on the bobbin iu the active Elli/ill tle, and on the substantial exhaustion of filling to put into operation mt'ichanism to cause the weft replenishing;- mechanism to supply a fresh bobbin in place of the substantially exhausted bobbin, in the usual and well known way.

The object of my invention "is to improve upon the construction of filling detector mechanisms of the class referred to, and more nirticularly toprovide a very sensitive and delicate detector mechanism, having a i'eeler which will feel for and de teet. the praetieal or substantial exhaustion of lilting on the bobbin without regard to the size. of the bobbin on which. the filling is wound, or the position of the bobbin inthe shuttle.

in my improvements I provide a feelerdcviee consisting of two members. One of said members is in the form of a slide suitably guided in a stand, and is yicldingly held against the lilliug on the bobbin on the fol-11rd movement oi the lay, and move. with the bobbin a certain distance toward the front of the loom as the lay beats up: said sliding member has preferably a broad engaging surf-ice, preferably rectangular in shape, relative. to the. length oi the bobbin, to engage the bobbin on its greatest diameter. The movement of the slide toward the breast beam or the front of the. loom causes a lever, to be hereinafter described, to be rocked, which causes the pivot point of an operating;- lever to be removed, and leaves the replenishing mechanism .at rest as long as a. sullicient amount of filling is left on the bobbin.

The second member of the feeler device toward the engaging end of the slide, and

consists in this instance of an angle lever. which is suitably pivoted on the first memher or slide. and has its engagingend located in substantially the same lmrizontal plane as the. engaging end of the lirst mew tioned member of the fender device. )nc arm of the angle lever extends preferably is also adapted to engage the filling on the bobbin. The end of Saidarm is in this ino stance tn'eferably provided with short bristles forming a brush surface. which will, in engaging the bobbin, penetrate the filling; without spoiling or inj'urin' the yarn. in my ii'eeler device, one ot the .lilling; engaging portions is adapted to be. moved away from and toward the other filling engaging portion, in the direction or the. bobbin or filling 'arrier. Upon the engagement of the bobbin by the tfeeler, both members will move in unison until substantial exhaustion of the filling is reached. Upon the substantial exhaustion offilling on the bobbin, When the sliding member engages the bobbin, there will not be a sufiicient amount of filling on the. bobbin to hold the. arm of the second member or angle lever stationary, this will allow said arm to move freely sidcwise, and through connections to a lever, hereinafter described, cause said lever to remain in its position and not act to withdraw the pivoted point of the. operating lever of the re. plenishing mechanism, and a fresh bobbin will be. dropped from the magazine in the usual way.

l have shown in the drawings a detached portion of a statiomu-y magazine, and some of the operating parts, of the type shown and described in U. S. Letters Patent No. 933,492, dated September 7, i909, with my improvements combined therewith, sufiicient to enable those skilled in the art to understand the construction and operation thereof.

Referring to the drawings :-Figure l is an end view of a detached portion of a Weft replenishing loom, with my improved filling detector mechanism combined therewith, looking in the direction of arrow a, Fig. 7 the lay, shuttle, and bobbin are shown in see tion. and the magazine shown in Fig. 7 is not shown in this figure. Fig. 2 shows some of the parts detached, which are not fully shown in Fig. 1. Fig. 3 is a plan viewer the filling feeler or detector, looking in the direction of HII'OXOV 7), Fig. 1, the transferrer arm shown in F ig. l is leftott in this figure. Fig. 4c shows the sliding part (it the feeler mechanism shown in Fig. 3, detached, and. in a different position. Fig. is afront View of the feeler slide, detached, looting in the direction of arrow 0, Fig. l. Fig. 9 is a section through the feeler slide, detached, on line 6, (3, Fig. 4t, looking in the direction of arrow 0, same figure. Fig. 7 is a front View of the parts shown in Fig. 1, looking in the direction of arrow (l, same figure, and also shows a stationary magazine and other parts of the type shown and described in said Letters Patent, No. 933,492, and, Fig. 8 is a detached portion of the stationary magazine shown in Fig. 7, showing a locking device for the upright bars combined therewith.

I will first describe my improvements in filling detector mechanism.

Secured to the loom side 1 and extending out therefrom, l1. stand 2, having a boss 2 and a stud orvbolt 3 thereon, Figs. 1 and 2. The stud 3 is provided with a bushing a, preferably secured thereon by a nut 5 see Fig. 5. The bushing 4 has adjustably secured thereon by a bolt 6, see Fig. 1, the clamping portion 7 of the t'eeler guide 7. The guide 7 preferably rests with its end upon an adiusting screw 8, and is grooved to loosely'receive the feelcr slide 9. A cap 10 is preferably secured upon the guide 7 by screws 11. The feeler'slide 9 is made in this instance of thin sheet metal, forming an oblong hollow member, see Fig. 5, which has a solid engaging end 9, with one or' more wedge shaped surfaces, adapted to an gage the bobbin 12 in the shuttle 13, through an opening 13 in the side of said shuttle, as shown in Fig. 3. The teeler slide 9 is one member of the feeler device, and the engagin end 9' is elongated or of considerable thickness, as shown in Fig. l, to engage a considerable surface of the filling, transversely of the bobbin. The slide 9 is provided With 9. lug 9", to hold the wire or rod 14 which extends through a lug 10 on the cap 10. A helically coiled expansion spring 15 encircles the rod 14, and bears at one end against the lug 10 on the cap 10, and at its other end against the lug 9 of the slide 9, and acts to yieldingly move the slide 9 toward the bobbin 12 in the shuttle 13, to engage with the filling 12 on said bobbin. An adjusting screw 16, which turns in a threaded. hole in an extension 10 on the inner end of the cap 10, serves to regulate the outward movement of the slide 9. By the engagement of the engaging end of the slide 9 with the bobbin 12 in the shuttle 13, a backward sliding movement is communicated to said slide every other pick, when the lay heats up.

Within the hollow part of the slide '9 is in this instance located the second surface, vulcanized fiber may be substitute-d. The second arm 17 of the angle lever 17 is oivotally connected to one end of a connc rod or wire 18, see 3 and 4-. and the other end OfStllCl rod 18 is "otally connected to the end of upright lever 19, F l, which has its hub 19 fast on a shaft 26 which loosely mounted in bosses 2 2 on the stand 2. A helicallv coiled torsion spring 21 encircles the sham; 20, and has one end connected with the hoss. 2, and the other end connected to a 22 fast on the shaft 20, see Fig. 5. The torsion SDZTiIlD' rocks the shaft i 4 L a and moves the lever 19, and the rod 18 attached thereto, to operate the angle lever 1?", when the slide 9, upon its engagementwith the bobbin 12, is moved toward the front of the loom. If there is not a suftlcient amount of fil ing 12 on'the bobbin 12 to hold the brush portion 1? on the lever '17, the engaging of said lever 1'4" will move outwardly, as shown in Fig. 3, and the upright lever will remain stationary in the position shown in Figs. 1 and The other end of the shaft 20 has secured thereon the hub 23 of an upright lever 23. The upper end of the upright l ver 23 is pivotally connected with the end of a horizontally extending rod 24;, see Fig. 3, which is loosely guided in the enlarged portion 2 the stand 2. The rod 24: extends into the lower part of the slotted recess in the stand F2, see l, and is adapted to form a rest or support for the end or a horizontally extending lever 25, which extends'into the slotted portion 2 and rests upon the end of the rod 24, see Fig. 5. The lever 25 has a vertical reciprocating movement commnni cated thereto from some driven part of the loom, not shown, through a connector 26 provided with a rod-head 26, which is loosely guiced in the boss 2 on the stand 52. The rod-head 26 carries a stud 27 on which the lever 25 is pivotally mounted, see Fi The other end of the lever 25 is pivotally connected to the lower end of an upwardly extendin connector 28, and the upper end of said connector 28 is pivotally connected to the end of a rocking lever 29, which op lever 30, to raise the upright bar 521 to rock the cradle 32, s e (5, all as .1.

it will be understood that the details of construction of my improvements tray be varied if desired. Instead of having a brush portion or bristles 17 on the fillingeugagmg end of the :2 igle lever 17, forming the second member of the feelcr device I may provide said end with any other suitable friction surface, as vulcanized fiber.
